A special set for a brand-new role. Celebrate the proud promotion to Big Brother status with our personalised ‘Big Brother’ pyjama set - made for the little one who’s about to take on the most important job in the family. Featuring their name alongside ‘Big Brother’, this set makes bedtime feel extra special (and helps them feel just as important as the new arrival). These PJs are perfect for post-bath cuddles and storytime snuggles. The classic colour-block sleeves and matching bottoms bring a playful touch, while easy shoulder poppers and a comfy elastic waistband make dressing or changing simple for busy parents. Whether it’s for a sibling announcement, hospital visit, or those first photos together, this set is a sweet reminder that every big brother deserves to feel loved, proud and part of the adventure.
